Let

0 &lt; \alpha &lt; {\pi \over 2}

be fixed angle. If

P = \left( {\cos \theta ,\,\sin \theta } \right)

and

Q = \left( {\cos \left( {\alpha - \theta } \right),\,\sin \left( {\alpha - \theta } \right)} \right),

then

Q

is obtained from

P

by

A clockwise rotation around origin through an angle $\alpha$
B anticlockwise rotation around origin through an angle $\alpha$
C reflection in the line through origin with slope tan $\alpha$
D reflection in the line through origin with slope tan $\left( {\alpha /2} \right)$
